WILLIAM T. MURPHY, OF NEW YORK, N. Y.

LAMP.

' SPECIFICATION forming part of Letters Patent No. 255,805, dated April 4, 1882.

Application died January 12, 188:2. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM T. MURPHY, a citizen of the United States, residingin the city, county, and State of New York, have invented certain Improvements in Lamps, of which the following is a specification.

My invention relates to a lamp comprising an oil fount or receiver made of glass, a hollow cylinder made of glass, metal, or other material, and a base or stand of metal or other suitable material. In this class of lamps the oil receiver is suspended within the hollow cylinder, and is supported thereby, and the cylinder rests on the base or stand.

The object of my invention is to hold the glass oil-receiver within the hollow cylinder in such a manner that when united they will be held firmly and securely together. To accomplish this I provide a metal ring or band made to fit on and around the upper end or neck of the cylinder. This ring or band is held down by being pressed tightly under a projecting rim or ledge on the oil receiver, which is also made to conform in size to and fit the ring or band. This construction prevents the overflow of oil from running inside the cylinder, which is very necessary when the cylinder is made of glass and decorated inside. The ring or band of metal may be madeto rest on the rim or flange of the cylinder, and be kept in position by the oil-receiver being pressed or held down upon'it. I prefer, however, to form an internal head on the metal ring or band to rest on the top of the cylinder, and for the oil receiver to rest upon, whereby the said head will be clasped between the oil-receiver and the cylinder. By this construction the glass receivcr'is prevented from coming in contact with the edge of the cylinder, and a certain amount of spring or elasticity is obtained, which will prevent the glass from breaking by jarring, 850.

The oil-receiver can be held in place in the cylinder by any of the well-known methods. I. prefer to employ one of the simplest-namely, a screw-threaded rod attached to the oilreceiver, as by this means one fastening serves to secure the oil-receiver in the cylinder, keeps the metal ring or band in place, and at the same time holds on the foot or base of the lamp.

In the drawings, Figure 1 is a vertical midsection of a lamp embodying myimprovements in the preferred form. Fig. 2 is an elevation, partly in section and on a smaller scale, showing a modification; and Fig 3 is an enlarged sectional detail designed to illustrate a modification.

A is the glass oil-reservoir. B is the cylinder. 0 is the foot or base. D is a metallic band or ring provided with an internal head, a. b is the screw-threaded rod, secured to the oil receiver and passing down throughthe foot (J and c is a nut on said rod, which secures all of the parts tightly together.

One object of the invention is to have the oil-receiver made from clear or semi-transparent glass, so that the oil can be seen either through the top of said receiver when the cylinder is madefrom opaque material, or through the cylinder when the latter is made from red, blue, sanded, or semi-transparent glass.

In some cases the band D may be widened to form a cylinder which extends down over the cylinder B, as shown in Fig. 2, and this metal cylinder may have ornamental slits or apertures formed in it, so that when the lamp is held up to the light the oil may be seen. By this method one may ascertain when the lamp needs oil, whereas in all cylinder-lamps as now made,so far as I am aware, the burner must be removed toascertain it the oil-receiver needs filling or not.

Fig. 3 shows the metal band D unpro'vided with a head, the' said band resting directly upon ashouldcr on the cylinder and under a shoulder on the oil-receiver.

I am aware that the means employed for securing the parts together-that is to say, the rod 1) and nut c-are not new. These have been employed tosecure together a foot, a

lamp-body, and a cylindrical intermediate stem. And I am also aware that a lamp havin g a movable bowl or reservoir for the oil, arranged to set into aholder, has been provided with a metallic'spring or cushion interposed between the edge of the holder and the bowl. This construction difi'ers, however, materially from mine, as it ofi'ers no obstacle to the overflow of oil getting into the hollow of the support, and the parts are not secured togetherin any way.

What I claim as my invention is-- 1. In an oil-lamp wherein a foot or base, a hollow cylinder, and-an oil-receiver of glass snspendedin the said cylinder are employed and all secured firmly together, the combinetion,with the said base, cylinder,and receiver, of a metal ring or band, D,arranged exteriorly around parts of the said receiver and cylinder and clamped between projecting parts of the same, substantially as set forth.

2. In an oil-lamp, the combination of the glass receiver A, the hollow cylinder B, the bnndor ring D, provided with an internal bead,

a, arranged between the receiver and cylinder, thelamp-base, and means for securing the parts firmly together, as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing r5 witnesses.
